Samples exhibited a characteristic ‘‘J’’ influence non-linear stress-strain response, with stiffness increasing with utilize strain. The cords were labelled with rows of lesser markers and the uniaxial tension tests were recorded via video. subsequent image analysis enabled the scattering of strain on the cord surface to be determined. elastic models were developed to model the mechanically skillful behaviour of the specimens and were found to adequately describe the material behaviour. r 2004 Elsevier Ltd.

Introduction The consider of the mechanical properties of the spinal cord is useful for the analysis and fellow feeling of the biomechanics of spinal cord injury (SCI), chronic cord abridg ement syndromes (e.g. degenerative spine dis! ease or syringomyelia), and of the spinal cord’s response to sub-injurious loading such as those go through and through during normal motion (Yuan et al., 1998). It is perhaps surprising therefore that secondary winding research has been undertaken into the mechanical response of spinal cord to loading, at either normal or abnormal physiological...If you want to travel a full essay, order it on our website: OrderEssay.net
